Match the following columns:

Column I (Crop)	Column II (Method of hybrid seed production)
a. Brinjal	1. Genetic male sterility
b. Chilli	2. Self incompatibility
c. Cucumber	3. Functional male sterility
d. Cabbage	4. Gynocracy

Solution(By Examveda Team)

a. The method of hybrid seed production of Brinjal is through Functional male sterility. In functional male sterility, viable pollens are formed but the barrier prevents fertilization.
b. Male sterility in chili is commercially utilized to develop hybrids and substantial progress has been made in understanding the mechanism of male sterility. It is generally characterized by the impairment of male reproductive development as a result of underlying genetic causes and leads to the malformation of male gametes and/or pollen.
c. Cucumber, Cucumis sativus is an important vegetable crop, and gynoecy has played a critical role in the yield increase of hybrid cucumber production. Cucumber has a unique genetic system for gynoecious sex expression, which is determined by the copy number variation based, and dosage-dependent femaleness (F) locus.
d. Self-incompatibility is a widespread mechanism in flowering plants like cabbage that prevents inbreeding and promotes outcrossing. The self-incompatibility response is genetically controlled by one or more multi-allelic loci and relies on a series of complex cellular interactions between the self-incompatible pollen and pistil.
